WEATHER-STRIP.

SPECIFICATION' forming part of Letters PatentNo. 546,256, dated September 10, 1895.

Application tiled May 31, 1895.

Be it known that I, JACOB M. MARGH, a citizen of the United States, and a resident of Narberth, Montgomery county, Pennsylvania, have invented certain Improvements inv WeathenStrips, of which the following is a specification.

The object ot my invention is to so oonstruct a weather-strip that it will iit tightly in the corner formed by the window and frame when the window is down, but as soon as the window is raised one part will move away from the other, so that the window can be raised without undue friction.

A further object of my invention is to secure the parts together that form the Weatherstrip in such a manner that the strip can be readily applied to the window by an unskilled mechanic and can be so folded that the strips can be packed in asrnall compass.

In the accompanying drawings, Figure l is a perspective View of a short section of my improved Weather-strip. Fig. 2 is a-s ection on the line 2 2, Fig. l. FigQS is an end view showing the sections folded for shipment. Fig. 4c is a perspective view illustrating the application of my invention to a window. Fig. 5 is a sectional view of a window-frame, show ing the Weatherstrip attached, the windowsash being in the closed position. Fig. 6 is a view similar to Fig. 5, showing the sections ot the weather-strip parted, the window-sash being raised. Fig.' 7 is a View of the strip, showing one section detached. Fig. S is a View of a modification of iny invention.

A is the weatherstrip, which is adapted to t into the corners b at the junction of the sash B with the frame B', as clearly illustrated in Figs. el. and 5. I

The weather-strip is composed of three sections ad a2, the section a being triangular in cross-section and tapered throughout its length, the distance from the point .fr to the back to varying, as clearly indicated in Figs. l and 2. The edges y of the strips a' and a2, which bear against the back of the strip d, are beveled on the saine line as the back rv', while the width of the entire weather-strip does not vary, the edges .e e being always the same, so that when the Weather-strip is attached to the window sash and frame its edges are parallel with the lines of the window sash Serial No. 551,137 (No model.)

and frame, the beveled portion not being exposed. l

In order to hold the severa-l strips together during shipment or while on sale, I secure at. intervals to the strips a band d, of fabric or other yielding material, which can be cut so as to separate one of the strips from thecenter strip ct,- as shown in Fig. 7, the other strip re maining attached to the center strip. It, for instance, the weather-strip is to beattached to a win dow, as shown in Fig. 5, the section c is separated from the section a, and the section a2, with lthe section d attached, is secured to the window-frame B by brads or screws, the section a fitting snugly into the corner formed by the window sash and frame, but not forced into the corner to such an extent as to prevent the easy Working ot the sash. The strip a is so arranged that its wide end is at the bottom of the Window-frame. The strip a is adjusted in position and forced tightly against the strip ct, so as to malte a tight iit, and is then secured to the windowsash by brads, screws, or other fastenings, as shown in Fig. 5. Soit will be seen that when the sash is down, as indicated in said figure, the weather-strip excludes the air, making a tight tit at the corner; but as soon as the sash is raised the section a' will be drawn away from the section a, as shown in Fig. 6,so that thewindoW-sash can beraised without undue friction.

It will be seen that by simply turning the Weather-strip around and detaching the section a2 from the section a the strip will it properly on the opposite side of the Window, the strip a2 being secured to the sash and the strip ct being secured to the frame. I

In some instances the band CZ may extend the full length of the strip, and, when necessary, the back of the strip d may be covered with felt, or the entire strip a may be incased in felt or other suitable material.

In some instances the corner piece may form part of one of the side strips, as shown in Fig. 8, there being sufficient yield in the strip to enable the other side strip to force the corner piece into the corner when the window-sash is down.

I claim as my invention- 1. The combination in a Weather strip, of the triangular cornersection adapted to iit in the corner of the window and having :L tapered back, with a bearing strip adapted to rest against the back of the corner strip and to force it into the corner when the window is closed, substantially as described.

2. rThe combination of a Weather strip made of three sections, the angular corner section adapted to the corner of the window and tapered at the baclgwith side strips adapted to rest against the back of the corner strip, one side strip and the corner strip being secured to the frame or sash and the other side strip being secured to the other part, substantially as described.

3. The combination of the triangular corner strip having a tapered back and side strips adapted to the back, one side strip being movable independent. of the corner strip, substantially as described.

4. The combination of the three strips, the cent-rai strip having the tapered back against which the side strips rest,with tapes binding the said strips together, substantially as described. v

In testimony whereof I have signed my name to this specification in the presence of two subscribing,T Witnesses.
